The multiple derivatives of position

[albertrichardf]

Hi all,
I came across the term placement, and presentment and the likes. I was wondering what they may mean in physics. I tried a search but the answers were not very clear. I was also wondering what action means in physics.
Any answers will be appreciated. Thanks

I have not seen the terms placement and presentment used as technical terms in physics. Placement is just where and how you put something ... like placement of table ware at a banquet, Presentment is how somethig is presented .. perhaps its orientation. These are both English descriptive terms; just follow the dictionary definitions.

Action is a technical term from physics. It is used in mechanics and quantum mechanics. Plank's constant has units of action.
